I'm attempting to replicate the required JavaScript banner on this site, and I have the following divs set up to be hidden if JavaScript is allowed/enabled. However, I am experiencing a fleeting glimpse of it upon page load.

<div id="Main_noJS">Craftystuff.com functions best with JavaScript enabled</div>
<div id="PartOfMain_noJS"><br /></div>

CSS:

#Main_noJS {
    width: 100%;
    height: 23px;
    font-family: Arial;
    font-size: 111%;
    color: White;
    font-weight: bold;
    background: #AE0000;
    text-align: center;
    padding-top: 4px;
    position: fixed;
    z-index: 100;
}

JavaScript:

// hide the "Craftystuff.com functions best with JavaScript enabled" banner, if JavaScript is working
if ($("#Main_noJS")) {
    $("#Main_noJS").hide();
    // hide the spacer between the main content and banner...
    $("#PartOfMain_noJS").hide();
}

So initially, the banner is visible, and only when JavaScript is enabled do I hide it.

  • However, there's a slight delay as JavaScript kicks in to hide things...

I'd like to find a way to prevent that initial glimpse of the banner when the page first loads. Any suggestions?

Answer №1

Insert the advertisement into a <noscript> element, details can be found here.

<noscript>
   <div>blah blah blah</div>
</noscript>

Answer №2

To effectively conceal an element while the website is loading, you can implement a tag that hides it until the script runs:

<script>document.write('<div style="display:none;">');</script>
<div id="Main_noJS">Experience the full functionality of Craftystuff.com with JavaScript enabled</div>
<script>document.write('</div>');</script>
